MAGNETIC AND ELECTRIC LOW FREQUENCY SHIELDING (DC - 30 MHz)
Shielding enclosures are designed to protect individuals and equipment, against magnetic and electric low frequency fields radiation, originated from facilities such as electric transformers, power lines or railway facilities.
In an installation made with our protective solutions using MCL61 , G-Iron Superflex, Mu-metal or Stabolec, both the magnetic field (M) and the low-frequency electric field (E) are shielded simultaneously.
Magnetic field (M) is turned into the high permeability sheet. Maximum absorption capacity of the magnetic field is determined by magnetic flux saturation, which is usually set at 0.8 Tesla.
The ability to divert the magnetic field is given by the magnetic permeability (μ), which in turn varies depending on the magnetic field flux (B) exists.
For higher magnetic permeabilities, we have two possibilities: increase the number of sheets (overlaying with intermediation of an insulating material) or using thicker sheets (increase the amount of high permeability alloy).
